Abstract
INTRODUCTION Cirrhosis is one of the major causes of morbidity and mortality worldwide. Portal hypertension is the major contributor of cirrhosis-related complications and is defined as a hepatic venous pressure gradient (HVPG) > 5 mmHg. Measurement of HVPG is an invasive, difficult, and costly procedure. Therefore, it is only performed in specialized centers. Liver stiffness measured with transient elastography is one of the most studied noninvasive markers of portal hypertension, and spleen elastography has recently emerged as an important adjuvant tool. The development of a new probe (100 Hz) that more reliably reflect the grade of portal hypertension evaluated by spleen stiffness measurement has improved the accuracy of this technique. The aim of this work was to evaluate the accuracy of spleen stiffness with the new dedicated probe to predict the presence of high-risk varices, as well as to determine the ideal cutoff to predict it. METHODS Prospective study of cirrhotic patients admitted to upper endoscopy that were also submitted to liver and spleen elastography with the 100-Hz probe by the same blinded operator in a tertiary center. RESULTS We included 209 cirrhotic patients, with mean age of 61.9 years (±9.9), 77.0% male. The most common etiology was alcoholic liver disease (72.7%). The median value of liver elastography was 25.3 [4.5-75] kPa, and the median value of spleen elastography was 42.4 [7.6-100] kPa. At the cutoff of 53.25 kPa, we obtained sensitivity of 100% and specificity of 72.6% to predict high-risk varices, and, according to this cutoff, 133/175 of esophagogastroduodenoscopy could have been spared (76.0%), while according to Baveno guidelines, only 51/175 would have been spared (29.1%). CONCLUSION In the era of noninvasive exams, spleen elastography with the 100-Hz probe emerges as an excellent tool for prediction of presence of high-risk varices. At the cutoff of 53.25 kPa, spleen elastography avoids upper endoscopy for screening for high-risk varices, promising to be become part of the hepatologists' daily routine.

High accuracy of spleen stiffness measurement in diagnosing clinically significant portal hypertension in metabolic-associated fatty liver disease. Liver Int 2023. [PMID: 36912787 DOI: 10.1111/liv.15561] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 03/01/2023] [Accepted: 03/03/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND AND AIMS Spleen stiffness measurement (SSM) by vibration-controlled transient elastography (VCTE) has been tested in a limited number of studies versus hepatic venous pressure gradient (HVPG), especially with the 100 Hz spleen-specific module. The current study aims to evaluate the diagnostic performance of this novel module for detecting clinically significant portal hypertension (CSPH) in a cohort of compensated patients with metabolic-associated fatty liver disease (MAFLD) as the main aetiology and to improve the performance of the Baveno VII criteria for CSPH diagnosis by including SSM. METHODS This is a retrospective single-centre study including patients with available measurements of HVPG, Liver stiffness measurement (LSM) and SSM by VCTE with the 100 Hz module. Area under the receiver operating characteristic (AUROC) curve analysis was conducted to identify dual cut-offs (rule-out and rule-in) associated with the absence/presence of CSPH. The diagnostic algorithms were adequate if negative predictive value (NPV) and positive predictive values (PPV) were >90%. RESULTS A total of 85 patients were included, 60 MAFLD and 25 non-MAFLD. SSM showed a good correlation with HVPG (MAFLD: r = .74; p < .0001; non-MAFLD: r = .62; p < .0011). In MAFLD patients, SSM had a high accuracy in discarding/diagnosing CSPH (cut-off values of <40.9 and >49.9 kPa, AUC 0.95). The addition of these cut-offs in a sequential or combined approach to the Baveno VII criteria significantly reduced the grey zone (60% vs. 15%-20%), while maintaining adequate NPV and PPV. CONCLUSIONS Our findings support the utility of SSM for diagnosing CSPH in MAFLD patients and demonstrate that the addition of SSM to the Baveno VII criteria increases accuracy.

Abstract
BACKGROUND AND AIMS We studied splenic stiffness measurement (SSM) by transient elastography (TE) and portal hemodynamics parameters (PHDp) on Doppler as predictors of clinically significant varices (CSV) in children. METHODS All children of 6 months to 18 years of age with portal hypertension (PHT) (chronic liver disease, CLD and non-cirrhotic portal hypertension, NCPH) were enrolled. TE for spleen (SSM) and liver (liver stiffness measurement, LSM) and PHDp by Doppler ultrasonography were measured. Noninvasive indices for PHT were calculated. CSV were defined as esophageal varices ≥grade 2 and/or gastric varix. Binary logistic regression analysis (LRA) and receiver operating characteristic statistics were applied. RESULTS A total of 150 (120 CLD and 30 NCPH) children formed the study cohort. Prevalence of CSV was higher in NCPH than CLD [73.3% vs 53.3%, Odd's ratio (OR) 2.369, P = 0.04]. On LRA, SSM was found to be the only independent predictor of CSV in children with CLD [OR 1.19 (95% Confidence Interval (CI) 1.018-1.16), P = 0.000] as well as in NCPH [OR 1.088 (95% CI 1.018-1.16), P = 0.013]. This model improved prediction of CSV in CLD from 52.5% to 83.9% and in NCPH from 73.3% to 86.7%. In children with CLD, SSM at a cut-off ≥27.6 kPa and in NCPH, SSM at a cut-off ≥29.5 kPa predicted CSV. In children with CLD, SSM correlated with LSM ( R = 0.610, P <0.001) and with noninvasive PHT indices except aspartate aminotransferase-to-platelet ratio index. CONCLUSION SSM is the best noninvasive predictor of CSV in childhood CLD and NCPH and can be used as screening test for endoscopy in children with PHT.

Abstract
This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To assess the diagnostic accuracy of liver stiffness and spleen stiffness, separately or in combination, as measured by vibration‐controlled transient elastography (VCTE) in detection of any oesophageal varices in adults with chronic liver disease. We will regard a combination of tests as positive when at least one is positive. To compare the diagnostic accuracy of individual tests (liver stiffness and spleen stiffness measured by VCTE) directly and versus the combination of both tests (considering positive when at least one is positive) in detecting any oesophageal varices. To assess the diagnostic accuracy of liver stiffness and spleen stiffness, separately or in combination, as measured by other elastography techniques (2D‐shear wave elastography (2D‐SWE), point shear wave elastography (pSWE), magnetic resonance elastography (MRE)) in detection of any oesophageal varices in adults with chronic liver disease. We will regard a combination of tests as positive when at least one is positive. To compare the diagnostic accuracy of liver stiffness and spleen stiffness measured by VCTE with other techniques (pSWE, 2D‐SWE, MRE) in detection of any oesophageal varices in adults with chronic liver disease.

Baveno criteria perform better than expanded Baveno and Rete Sicilia Selezione Terapia-Hepatitis C virus criteria for predicting varices needing treatment. Indian J Gastroenterol 2021; 40:590-597. [PMID: 33991311 DOI: 10.1007/s12664-020-01141-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 12/15/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Endoscopy is the gold standard for the detection and staging of varices. Baveno, expanded Baveno, and Rete Sicilia Selezione Terapia-hepatitis C virus (RESIST-HCV) criteria predict varices non-invasively in patients with cirrhosis. We assessed the performance of these criteria for predicting varices needing treatment (VNT). METHODS Consecutive patients with compensated cirrhosis due to viral etiologies evaluated between January 2014 and May 2017 were included in this retrospective analysis of a prospectively maintained database. VNTs were defined as either large varies or small varices with red color signs on endoscopy. Performance characteristics to predict VNTs were estimated for the three criteria and spared endoscopy rate (SER) and missed VNT rates were determined. RESULTS Two hundred and ninety-five treatment-naïve cirrhosis patients, etiology hepatitis B (n = 154) or hepatitis C (n = 141), mean age 43.1 ± 13.2 years, 127 (43.1%) males were included. The median liver stiffness measurement (LSM) and platelet counts were 19.7 (interquartile range [IQR]: 14.8-28.8) kPa and 119 (IQR: 80-160) × 103/mm3, respectively. The SER and missed VNT rates were as follows-for Baveno criteria: 18.3% and 6.2%; expanded Baveno: 35.3% and 29.2%; and for RESIST-HCV criteria: 37.3% and 22.9%. The sensitivity, specificity, positive predictive value, and negative predictive value were 93.7%, 21.9%, 18.9%, and 94.7% for Baveno criteria; 70.8%, 42.3%, 19.3%, and 88.1% for expanded Baveno; and 77.1%, 44.5%, 21.3%, and 90.9% for RESIST-HCV criteria, respectively. CONCLUSION Baveno criteria are useful to avoid screening endoscopies in patients with cirrhosis of viral etiologies. In contrast, although expanded Baveno criteria and RESIST-HCV criteria spare more endoscopies, a high missed VNT rate limits their applicability.

Abstract
Patients with compensated advanced chronic liver disease have different prognoses depending on the presence of portal hypertension. Current non-invasive diagnostic methods allow identification of clinically significant portal hypertension. Portosystemic collaterals on imaging or liver stiffness of more than 20 to 25 kPa by using transient elastography identifies patients with clinically significant portal hypertension. Patients with liver stiffness of less than 20 kPa and platelet count of greater than 150 g/L can avoid endoscopy. This rule could be expanded using spleen stiffness. Methods to risk stratify for portal hypertension in compensated advanced chronic liver disease and successfully treated chronic hepatitis C and B are subject of research.

Abstract
INTRODUCTION The aim of this study was to investigate the accuracy of liver and spleen stiffness measurement by transient elastography for the prediction of gastroesophageal varices in patients with HCV-associated cirrhosis treated with new direct-acting antiviral agents. PATIENTS AND METHODS This cross-sectional observational study included patients with compensated HCV-related cirrhosis and sustained virological response after direct-acting antiviral therapy. Patients underwent liver and spleen stiffness measurement, abdominal ultrasound and oesophago-gastroduodenoscopy. Clinical and laboratory data and non-invasive markers such as the liver stiffness-spleen diameter to platelet ratio score, variceal risk index and platelet count to spleen diameter ratio were analyzed. RESULTS Ninety-seven consecutive patients were included. Liver stiffness measurement (12.2 vs 16; p=0.02), spleen stiffness measurement (39.4 vs 46.05; p=0.04), liver stiffness-spleen diameter to platelet ratio score (1.21 vs 2.02; p=0.008), platelet count to spleen diameter ratio (1102.19 vs 829.7; p=0.04) and variceal risk index (-3.4 vs -1.02; p=0.01) showed significant differences between patients without/with gastroesophageal varices. The best cut-off value to discard the presence of gastroesophageal varices was 12.3kPa for liver stiffness measurement and 27kPa for spleen stiffness measurement. However, diagnostic accuracy was moderate (AUROC: 0.671 and 0.624 respectively). Combining different non-invasive parameters did not significantly improve the overall performance. DISCUSSION Liver and spleen stiffness measurement showed suboptimal results for non-invasive assessment of gastroesophageal varices in HCV cirrhotic patients treated with direct-acting antiviral agents. Our results suggest that non-invasive methods cannot substitute standard procedures for predicting gastroesophageal varices in this population.

Abstract
Objectives To systematically review studies on the diagnostic accuracy of spleen stiffness measurement (SSM) for the detection of clinical significant portal hypertension (CSPH), severe portal hypertension (SPH), esophageal varices (EV), and high-risk esophageal varices (HREV) in patients with chronic liver diseases (CLD). Methods Through a systematic search, we identified 32 studies reporting the accuracy of SSM for the diagnosis of portal hypertension (PH) and/or EV in adults with CLD. A bivariate random-effects model was performed to estimate pooled sensitivity, specificity, likelihood ratio, positive predictive value (PPV), negative predictive value (NPV), and diagnostic odds ratios (DOR). The clinical utility of SSM was evaluated by Fagan plot. Results A total of 32 studies assessing 3952 patients were included in this meta-analysis. The pooled sensitivities of SSM were 0.85 (95% confidence interval (CI), 0.69–0.93) for CSPH; 0.84 (95% CI, 0.75–0.90) for SPH; 0.90 (95% CI, 0.83–0.94) for any EV; and 0.87 (95% CI, 0.77–0.93) for HREV. The pooled specificities of SSM were 0.86 (95% CI, 0.74–0.93) for CSPH; 0.84 (95% CI, 0.72–0.91) for SPH; 0.73 (95% CI, 0.66–0.79) for EV; and 0.66 (95% CI, 0.53–0.77) for HREV. Summary PPV and NPV of SSM for detecting HREV were 0.54 (95% CI, 0.47–0.62) and 0.88 (95% CI, 0.81–0.95), respectively. Conclusions Our meta-analysis suggests that SSM could be used as a helpful surveillance tool in management of CLD patients and was quite useful for ruling out the presence of HREV thereby avoiding unnecessary endoscopy. Key Points • SSM could be used to rule out the presence of HREV in patients with CLD thereby avoiding unnecessary endoscopy. • SSM has significant diagnostic value for CSPH and SPH with high sensitivity and specificity in patients with CLD. • SSM could be used as a helpful surveillance tool for clinicians managing CLD patients.

Abstract
Variceal bleeding is a dramatic complication of cirrhosis. Primary prophylaxis against variceal bleeding is indicated for patients with high-risk varices. In order for these patients to be identified, endoscopic screening for esophageal varices has been traditionally recommended at the time of the diagnosis of cirrhosis. Considering that many patients do not have esophageal varices in the early stages of cirrhosis and, therefore, are submitted to endoscopy unnecessarily, non-invasive methods for variceal screening have been studied. Among these non-invasive methods, the most extensively studied probably are platelet count/spleen diameter ratio, liver stiffness, spleen stiffness and an association between liver stiffness and platelet count, referred to as the Baveno VI criteria. The Baveno VI criteria has recently been recommended by different medical associations for variceal screening. This is a critical review on the non-invasive methods for variceal screening, in which the performances of the different methods are presented and the limitations of the existing evidence is discussed. Despite reasonable performances of some of these methods, especially platelet count/spleen diameter ratio and the association between liver stiffness and platelet count, we understand that the available evidence still has relevant limitations and that physicians should decide on screening cirrhotic patients for esophageal varices with endoscopy or non-invasive methods on a case-by-case basis.

A novel spleen-dedicated stiffness measurement by FibroScan® improves the screening of high-risk oesophageal varices. Liver Int 2020; 40:175-185. [PMID: 31444849 DOI: 10.1111/liv.14228] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 07/23/2019] [Accepted: 08/20/2019] [Indexed: 02/13/2023]
Abstract
BACKGROUND & AIMS Several non-invasive tests (NITs) have been developed to diagnose oesophageal varices (EV), including the recent Baveno VI criteria to rule out high-risk varices (HRV). Spleen stiffness measurement (SSM) with the standard FibroScan® (SSM@50Hz) has been evaluated. However, the EV grading could be underestimated because of a ceiling threshold (75 kPa) of the SSM@50Hz. The aims were to evaluate SSM by a novel spleen-dedicated FibroScan® (SSM@100Hz) for EV diagnosis compared with SSM@50Hz, other validated NITs and Baveno VI criteria. METHODS This prospective multicentre study consecutively enrolled patients with chronic liver disease; blood data, endoscopy, liver stiffness measurement (LSM), SSM@50Hz and SSM@100Hz were collected. RESULTS Two hundred and sixty patients met inclusion criteria. SSM@100Hz success rate was significantly higher than that of SSM@50Hz (92.5% vs 76.0%, P < .001). SSM@100Hz accuracy for the presence of EV (AUC = 0.728) and HRV (AUC = 0.756) was higher than in other NITs. SSM@100Hz AUC for large EV (0.782) was higher than SSM@50Hz (0.720, P = .027). AUC for HRV with SSM@100Hz (0.780) was higher than with LSM (0.615, P < .001). The spared endoscopy rate of Baveno VI criteria (8.1%) was significantly increased by the combination to SSM@50Hz (26.5%) or SSM@100Hz (38.9%, P < .001 vs others). The missed HRV rate was, respectively, 0% and 4.7% for combinations. CONCLUSIONS SSM@100Hz is a new performant non-invasive marker for EV and HRV providing a higher accuracy than SSM@50Hz and other NITs. The combination of Baveno VI criteria and SSM@100Hz significantly increased the spared endoscopy rate compared to Baveno VI criteria alone or combined with SSM@50Hz. Clinical trial number: NCT02180113.

Spleen Stiffness as Predictor of Esophageal Varices in Cirrhosis of Different Etiologies. Sci Rep 2019; 9:16190. [PMID: 31700031 PMCID: PMC6838194 DOI: 10.1038/s41598-019-52407-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Accepted: 10/09/2019] [Indexed: 02/06/2023] Open
Abstract
The purpose of this study is to determine whether esophageal varices (EV) can be identified through the evaluation of spleen stiffness (SSM) via acoustic radiation force impulse (ARFI). A total of 135 patients suffering from cirrhosis underwent a clinical exam, laboratory tests, abdominal ultrasound, liver stiffness (LSM) measurement, SSM evaluation and upper gastrointestinal endoscopy. Based on the endoscopy results, the patients were classified into three groups: those with no evident EV, those with small EV and those with varices needing treatment (VNT). Patients with EV of any grade had significantly higher average SSM values over those with no EV (3.37 m/s versus 2.79 m/s, p-value < 0.001), while patients with VNT showed an even greater difference (3.96 m/s versus 2.93 m/s, p-value < 0.001). SSM proved to be an excellent method of predicting patients with VNT.

Prediction of esophageal varices by liver and spleen MR elastography. Eur Radiol 2019; 29:6611-6619. [PMID: 31041563 DOI: 10.1007/s00330-019-06230-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2018] [Revised: 04/05/2019] [Accepted: 04/08/2019] [Indexed: 12/18/2022]
Abstract
OBJECTIVES We aimed to assess the diagnostic performance of MR elastography (MRE) in predicting esophageal varices (EVs) in patients with chronic liver disease. METHODS We prospectively performed liver (LSM) and spleen stiffness measurements (SSM) using MRE and endoscopic screening for EVs to determine if patients with hepatocellular carcinoma were eligible for resection. We investigated whether LSM, SSM, and other non-invasive preoperative parameters were associated with the presence of EVs. In order to predict EVs, 211 patients were divided into training (n = 140) and test (n = 71) groups. A nomogram was built using independent factors based on logistic regression analysis in the training group and its accuracy was validated using an independent cohort. RESULTS Forty-six patients (21.8%) were diagnosed as having EVs (mild, n = 36; severe, n = 10). According to multiple regression analysis, LSM (odds ratio, 2.362; 95% confidence interval [CI], 1.341-4.923; p = 0.001) and SSM (1.489; 1.095-2.235; p = 0.010) were independent predictors of EVs in the training group. The nomogram showed good discrimination, with a C-index of 0.942 (95% CI, 0.892-0.974) through internal validation, and good calibration. Application of the nomogram in the test group still gave good discrimination (C-index, 0.948; 95% CI, 0.868-0.995). CONCLUSIONS The combination of LSM and SSM using MRE is an accurate tool to identify patients at risk for EVs. KEY POINTS • Performance of MR elastography can estimate the presence of esophageal varices non-invasively. • Liver and spleen stiffness measurements are independent predictors for esophageal varices. • The nomogram using a combination of liver and spleen stiffness measurements allows for the risk of esophageal varices.

Contrast-Enhanced CT May Be a Diagnostic Alternative for Gastroesophageal Varices in Cirrhosis with and without Previous Endoscopic Variceal Therapy. Gastroenterol Res Pract 2019; 2019:6704673. [PMID: 31781196 PMCID: PMC6855090 DOI: 10.1155/2019/6704673] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 08/20/2019] [Accepted: 09/06/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND AIMS Liver fibrosis blood tests, platelet count/spleen diameter ratio (PSR), and contrast-enhanced CT are diagnostic alternatives for gastroesophageal varices, but they have heterogeneous diagnostic performance among different study populations. Our study is aimed at evaluating their diagnostic accuracy for esophageal varices (EVs) and gastric varices (GVs) in cirrhotic patients with and without previous endoscopic variceal therapy. METHODS Patients with liver cirrhosis who underwent blood tests and contrast-enhanced CT scans as well as endoscopic surveillance should be potentially eligible. EVs needing treatment (EVNTs) and GVs needing treatment (GVNTs) were recorded according to the endoscopic results. Area under the curves (AUCs) were calculated. RESULTS Overall, 279 patients were included. In 175 patients without previous endoscopic variceal therapy, including primary prophylaxis population (n = 70), acute bleeding population (n = 38), and previous bleeding population (n = 67), the diagnostic accuracy of contrast-enhanced CT for EVNTs was higher (AUCs = 0.816-0.876) as compared to blood tests and PSR; by comparison, the diagnostic accuracy of contrast-enhanced CT for GVNTs was statistically significant among primary prophylaxis population (AUC = 0.731, P = 0.0316), but not acute or previous bleeding population. In 104 patients with previous endoscopic variceal therapy (i.e., secondary prophylaxis population), contrast-enhanced CT was the only statistically significant alternative for diagnosing EVNTs and GVNTs but with modest accuracy (AUCs = 0.673 and 0.661, respectively). CONCLUSIONS Contrast-enhanced CT might be a diagnostic alternative for EVNTs in cirrhotic patients, but its diagnostic performance was slightly weakened in secondary prophylaxis population. Additionally, contrast-enhanced CT may be considered for diagnosis of GVNTs in primary prophylaxis population without previous endoscopic variceal therapy and secondary prophylaxis population.

Abstract
BACKGROUND AND AIM There is increasing evidence of non-invasive measurement using elastography such liver stiffness (LS), spleen stiffness (SS), and LS-spleen diameter to platelet ratio score (LSPS) for detection of esophageal varices (EV); however, data regarding comparison between these three parameters are limited. METHODS We performed a systemic review and meta-analysis of studies evaluating performance of LS, SS, and LSPS for detection of EV and high risk/clinically significant EV (HREV). Pooled sensitivity, specificity, log diagnostic odd ratio (LDOR), and area under the receiver operating characteristic curve (AUC) of LS, SS, and LSPS for detection of EV and HREV were analyzed and compared. Publication bias was assessed by Deeks' funnel plot. RESULTS SS and LSPS were superior to LS for detection of EV with higher sensitivity (0.90 and 0.91 vs 0.85), specificity (0.73 and 0.76 vs 0.64), LDOR (3.24 and 3.35 vs 2.26), and AUC (0.899 and 0.851 vs 0.817). For HREV, SS had the highest sensitivity (0.87) followed by LS (0.85) and LSPS (0.82); however, SS had the lowest specificity (0.52), LDOR (2.09), and AUC (0.807) whereas LSPS had the highest specificity (0.77), LDOR (2.74), and AUC (0.861). CONCLUSION For detection of EV, we prefer using LSPS and SS over LS when available, while LS, SS, and LSPS cannot be recommended for detection of HREV due to their moderate sensitivity and specificity.

Abstract
Esophageal varices (EVs) are among the most severe complications of cirrhosis, with a prevalence of 50% to 60% among cirrhotic patients. International guidelines therefore recommend that cirrhotic patients should be screened for the presence of EVs. The main objective of this study was to introduce a new spleen-dedicated FibroScan (Echosens, Paris, France) examination and to assess its performance in detecting large EVs (grade 2 and 3). This novel examination has been validated in simulation and phantom studies and has been used in a population of patients with chronic liver disease. The study described here suggests that the novel spleen-dedicated FibroScan examination performs better than the standard FibroScan for the detection of large EVs (area under the curve = 0.70 for the standard examination and 0.79 [p <0.01] for the spleen examination), but further clinical studies are needed to investigate the role of spleen stiffness in the management of cirrhotic patients.

A combined model based on spleen stiffness measurement and Baveno VI criteria to rule out high-risk varices in advanced chronic liver disease. J Hepatol 2018; 69:308-317. [PMID: 29729368 DOI: 10.1016/j.jhep.2018.04.023] [Citation(s) in RCA: 122] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Revised: 04/14/2018] [Accepted: 04/18/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND & AIMS Recently, Baveno VI guidelines suggested that esophagogastroduodenoscopy (EGD) can be avoided in patients with compensated advanced chronic liver disease (cACLD) who have a liver stiffness measurement (LSM) <20 kPa and platelet count >150,000/mm3. We aimed to: assess the performance of spleen stiffness measurement (SSM) in ruling out patients with high-risk varices (HRV); validate Baveno VI criteria in a large population and assess how the sequential use of Baveno VI criteria and SSM could safely avoid the need for endoscopy. METHODS We retrospectively analyzed 498 patients with cACLD who had undergone LSM/SSM by transient elastography (TE) (FibroScan®), platelet count and EGDs from 2012 to 2016 referred to our tertiary centre. The new combined model was validated internally by a split-validation method, and externally in a prospective multicentre cohort of 115 patients. RESULTS SSM, LSM, platelet count and Child-Pugh-B were independent predictors of HRV. Applying the newly identified SSM cut-off (≤46 kPa) or Baveno VI criteria, 35.8% and 21.7% of patients in the internal validation cohort could have avoided EGD, with only 2% of HRVs being missed with either model. The combination of SSM with Baveno VI criteria would have avoided an additional 22.5% of EGDs, reaching a final value of 43.8% spared EGDs, with <5% missed HRVs. Results were confirmed in the prospective external validation cohort, as the combined Baveno VI/SSM ≤46 model would have safely spared (0 HRV missed) 37.4% of EGDs, compared to 16.5% when using the Baveno VI criteria alone. CONCLUSIONS A non-invasive prediction model combining SSM with Baveno VI criteria may be useful to rule out HRV and could make it possible to avoid a significantly larger number of unnecessary EGDs compared to Baveno VI criteria only. LAY SUMMARY Spleen stiffness measurement assessed by transient elastography, the most widely used elastography technique, is a non-invasive technique that can help the physician to better stratify the degree of portal hypertension and the risk of esophageal varices in patients with compensated advanced chronic liver disease. Performing spleen stiffness measurement together with liver stiffness measurement during the same examination is simple and fast and this sequential model can identify a greater number of patients that can safely avoid endoscopy, which is an invasive and expensive examination.

Abstract
BACKGROUD To assess the diagnostic performance of transient elastography (TE) in detecting the presence and size of esophageal varices (EV) in cirrhotic patients. METHODS We searched PubMed, Web of Science, Wiley Online Library, Science Direct, China National Knowledge Infrastructure, WeiPu, WanFang database, and Baidu Scholar to identify studies that evaluated the diagnostic accuracy of TE in liver stiffness measurement, compared with esophagogastroduodenoscopy (EGD), for the detection of the presence and degree of EV in cirrhosis. RESULTS We included 32 studies in the presence of any EV (grade 1-3; n = 4082), 27 studies on substantial EV (grade 2-3; n = 5221) and 5 studies on large EV (grade 3). The pooled sensitivity, specificity, and diagnostic odds ratio (DOR) were 0.8 (95% CI, 0.78-0.86), 0.68 (95% CI, 0.62-0.74), and 10 (95% CI, 7-14) for any EV; 0.81 (95% CI, 0.77-0.85), 0.72 (95% CI, 0.66-0.77), and 11 (95% CI, 8-15) for substantial EV; and 0.92 (95% CI, 0.83-0.96), 0.78 (95% CI, 0.70-0.85), and 40 (95% CI, 15-107) for large EV. Subgroup analysis revealed that the heterogeneity among studies on any EV could potentially be explained by study location, proportion of Child A, and time interval between TE and EGD; for substantial EV, the proportion of Child A, etiology of cirrhosis, and the time interval between TE and EGD were important heterogeneity factors. Publication bias was found among studies evaluating diagnostic performance of TE for any EV. CONCLUSION TE is a good tool for detecting the presence and degree of EV; however, in determination of the liver stiffness cutoff values means that TE is only cautiously used in clinical practice.

Abstract
Chronic liver diseases often result in the development of liver fibrosis and ultimately, cirrhosis. Treatment strategies and prognosis differ greatly depending on the severity of liver fibrosis, thus liver fibrosis staging is clinically relevant. Traditionally, liver biopsy has been the method of choice for fibrosis evaluation. Because of liver biopsy limitations, noninvasive methods have become a key research interest in the field. Elastography enables the noninvasive measurement of tissue mechanical properties through observation of shear-wave propagation in the tissue of interest. Increasing fibrosis stage is associated with increased liver stiffness, providing a discriminatory feature that can be exploited by elastographic methods. Ultrasonographic (US) and magnetic resonance (MR) imaging elastographic methods are commercially available, each with their respective strengths and limitations. Here, the authors review the technical basis, acquisition techniques, and results and limitations of US- and MR-based elastography techniques. Diagnostic performance in the most common etiologies of chronic liver disease will be presented. Reliability, reproducibility, failure rate, and emerging advances will be discussed. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
The gold standard to assess the presence and severity of portal hypertension remains the hepatic vein pressure gradient, however the recent development of non-invasive assessment using elastography techniques offers valuable alternatives. In this review, we discuss the diagnostic accuracy and utility of such techniques in patients with portal hypertension due to cirrhosis. Areas covered: A literature search focused on liver and spleen stiffness measurement with different elastographic techniques for the assessment of the presence and severity of portal hypertension and oesophageal varices in people with chronic liver disease. The combination of elastography with parameters such as platelet count and spleen size is also discussed. Expert commentary: Non-invasive assessment of liver fibrosis and portal hypertension is a validated tool for the diagnosis and follow-up of patients. Baveno VI recommended the combination of transient elastography and platelet count for ruling out varices needing treatment in patients with compensated advanced chronic liver disease. Assessment of aetiology specific cut-offs for ruling in and ruling out clinically significant portal hypertension is an unmet clinical need. The incorporation of spleen stiffness measurements in non-invasive algorithms using validated software and improved measuring scales might enhance the non-invasive diagnosis of portal hypertension in the next 5 years.

Abstract
Here, we review recent improvements made to different noninvasive tests used for the diagnosis of esophageal varices (EV) in the light of the recent Baveno VI recommendation and with an emphasis on clinical application. Like for fibrosis tests, these noninvasive EV tests can be classified as direct markers when they provide a visualization of EV (including all imaging procedures like endoscopy or radiology) and as indirect markers when they do not (blood markers or elastometry). Clinical descriptors expressed as percentages, especially the spared endoscopy rate and the missed high-risk esophageal varices (HREV) rate, are more eloquent in this setting than classical statistical descriptors like accuracy. Single biomarkers are insufficient, generally due to a missed HREV rate exceeding the acceptable limit of 5% indicated in the Baveno VI consensus. Thus, biomarker combinations are currently garnering the most interest. The Baveno VI recommendation states that in alcoholic and viral cirrhoses, screening endoscopy can be safely set aside for patients with liver stiffness<20kPa and platelets>150G/L. The Baveno rule's mean missed HREV rate is<5% but its spared endoscopy rate is<20%. New combinations or stepwise algorithms show promise but must be validated. Going forward, the Baveno rule provides a simple noninvasive method to rule out HREV in clinical practice but the need for further research continues. The noninvasive diagnosis of HREV will be significantly improved by new, simple and affordable combinations.

Abstract
BACKGROUND & AIMS Large oesophageal varice (LEV) screening is recommended in cirrhosis. We performed a prospective study to improve non-invasive LEV screening. DESIGN 287 patients with cirrhosis had upper gastrointestinal endoscopy (LEV reference), oesophageal capsule endoscopy (ECE), liver elastography and blood marker analyses. CirrhoMeter (cirrhosis blood test), the most accurate non-invasive LEV test, was segmented for cirrhosis (reference comparator) or LEV. VariScreen, a sequential and partially minimally invasive diagnostic algorithm, was developed by multivariate analysis. It uses CirrhoMeter first, then ECE if CirrhoMeter cannot rule LEV out or in, and finally endoscopy if CirrhoMeter+ECE combination remains uninformative. RESULTS Diagnostic effectiveness rates for LEV were: cirrhosis-segmented CirrhoMeter: 14.6%, LEV-segmented CirrhoMeter: 34.6%, ECE: 60.6% and VariScreen: 66.4% (P ≤ .001 for overall or pair comparison). The respective missed LEV rates were: 2.8%, 5.6%, 8.3% and 5.6% (P = .789). Spared endoscopy rates were, respectively: 15.6%, 36.0%, 70.6% and 69%, (P < .001 for overall or paired comparison except ECE vs VariScreen: P = .743). VariScreen spared 38% of ECE and reduced missed LEV by 87% compared to classical ECE performed in all patients. Excepting cirrhosis-segmented CirrhoMeter, these spared endoscopy rates were significantly higher than that of the Baveno VI recommendation (using platelets and Fibroscan): 18.4% (P < .001). Ascites and Child-Pugh class independently predicted endoscopy sparing by VariScreen: from 86.0% in compensated Child Pugh class A to 24.1% in Child-Pugh class C with ascites. CONCLUSION VariScreen algorithm significantly reduced the missed LEV rate with ECE by 87%, ECE use by 38% and endoscopy requirement by 69%, and even 86% in compensated cirrhosis.

Abstract
Portal hypertension is the central driver of complications in patients with chronic liver diseases and cirrhosis. The diagnosis of portal hypertension has important prognostic and clinical implications. In particular, screening for varices in patients with portal hypertension can effectively reduce the morbidity and mortality of variceal bleeding. In this article, we review the invasive and non-invasive methods to assess portal hypertension. Hepatic venous pressure gradient remains the gold standard to measure portal pressure but is invasive and seldom performed outside expert centers and research settings. In recent years, a number of non-invasive tests of fibrosis have shown good correlation with liver histology. They also show promise in identifying patients with portal hypertension and large varices. As a result, the latest Baveno VI consensus guidelines endorse the use of liver stiffness measurement by transient elastography and platelet count as initial assessment to select patients for varices screening. On the other hand, the performance of non-invasive tests in assessing the response to non-selective beta-blockers or transjugular intrahepatic portosystemic shunting is either suboptimal or unclear.

Abstract
Platelet count to spleen diameter ratio (PSR) was studied extensively as a noninvasive method of diagnosis for varices. The present study aimed to systematically assess the performance of PSR in the diagnosis of varices. PubMed, EMBASE, and article references were searched. The summary receiver operating characteristic curves (AUSROCs), sensitivities, specificities, positive and negative likelihood ratio, and diagnostic odds ratio were calculated. The heterogeneity, quality, and publication bias of studies were evaluated. Subgroup and sensitivity analyses were performed. A total of 49 papers were included. The AUSROCs of PSR for any varices and high-risk varices were 0.8719 and 0.8132, respectively. The summary sensitivities of PSR for any varices and high-risk varices were 0.84 and 0.78, respectively. The summary specificities of PSR for any varices and high-risk varices were 0.78 and 0.67, respectively. The AUSROC of PSR for any varices at the threshold of 909 was 0.8867. The AUSROC of PSR for any varices in viral liver cirrhosis was 0.8675. The overall quality of studies was moderate. Significant heterogeneity and publication bias existed in the study. In conclusion, PSR can be used to identify varices in liver cirrhosis. PSR had a high sensitivity in viral liver cirrhosis.

Abstract
Transient elastography and the acoustic radiation force impulse techniques may play a pivotal role in the study of liver fibrosis. Some studies have shown that elastography can detect both the progression and regression of fibrosis. Similarly, research results have been analysed and direct and indirect serum markers of hepatic fibrosis have shown high diagnostic accuracy for advanced fibrosis/cirrhosis. The prognosis of different stages of cirrhosis is well established and various staging systems have been proposed, largely based on clinical data. However, it is still unknown if either non-invasive markers of liver fibrosis or elastography may contribute to a more accurate staging of liver cirrhosis, in terms of prognosis and fibrosis regression after effective therapy. In fact, not enough studies have shown both the fibrosis regression in different cirrhosis stages and the point beyond which the prognosis does not change - even in the event of fibrosis regression. Therefore, future studies are needed to validate non-invasive methods in predicting the different phases of liver cirrhosis.

Abstract
Background and Aims Liver stiffness (LS) and spleen stiffness (SS) are two most widely accessible non-invasive parameters for predicting esophageal varices (EV), but the reported accuracy of the two predictors have been inconsistent across studies. This meta-analysis aims to evaluate the diagnostic performance of LS and SS measurement for detecting EV in patients with chronic liver disease (CLD), and compare their accuracy. Methods Pubmed/Medline, Embase, Cochrane Library and Ovid were searched for all studies assessing SS and LS simultaneously in EV diagnosis. A total of 16 studies including 1892 patients were included in this meta-analysis, and the pooled statistical parameters were calculated using the bivariate mixed effects models. Results In detection of any EV, for LS measurement, the summary sensitivity was 0.83 (95% confidence interval [CI]: 0.78–0.87), and the specificity was 0.66 (95% CI: 0.60–0.72). While for SS measurement, the pooled sensitivity and specificity was 0.88 (95% CI: 0.83–0.92) and 0.78 (95% CI: 0.73–0.83). The summary receiver operating characteristic (SROC) curve values of LS and SS were 0.81 (95% CI: 0.77–0.84) and 0.88 (95% CI: 0.85–0.91) respectively, and the results had statistical significance (P<0.01). The diagnostic odds ratio (DOR) of SS (25.73) was significantly higher than that of LS (9.54), with the relative DOR value was 2.48 (95%CI: 1.10–5.60), P<0.05. Conclusions Under current techniques, SS is significantly superior to LS for identifying the presence of EV in patients with CLD. SS measurement may help to select patients for endoscopic screening.

Abstract
BACKGROUND/AIM Transient elastography is a relatively new, noninvasive method of measuring liver stiffness. This study aimed to evaluate the diagnostic accuracy of transient elastography and other noninvasive methods for the diagnosis of esophageal varices (EV) in patients with cirrhosis. METHODS This cross-sectional study graded EV according to size in 145 consecutive patients with cirrhosis who underwent endoscopy, Fibroscan, and other noninvasive diagnostic methods. The accuracy of these diagnostic methods in diagnosing EV was evaluated on the basis of area under receiver operating characteristic (AUROC) curves. RESULTS Elastography was successful in 123 patients. Of these, 54.5% had hepatitis C and 10.6% had hepatitis B. EV were absent in 39.8%, small EV was present in 24.4%, and large EV was present in 35.8% of patients. Fibroscan, aspartate aminotransferase-to-platelet ratio index, and international normalized ratio showed low accuracy in diagnosing EV in non-viral-related cirrhosis patients (AUROCs 0.66, 0.68, and 0.67, respectively). Fibroscan and aspartate aminotransferase-to-platelet ratio index were more accurate in measuring EV with a viral etiology (AUROCs 0.704 and 0.703, respectively). A cutoff value of 16.9 kPa was 83.8% sensitive in diagnosing EV in non-viral-cirrhotic patients, whereas a cutoff value of 19.9 kPa was 83.4% sensitive in diagnosing EV in patients with viral hepatitis. Fibroscan was moderately accurate in diagnosing grade I EV and less accurate in diagnosing grades II and III EV in all cirrhotic patients, irrespective of the underlying etiology. CONCLUSION Fibroscan might be useful in predicting the presence of EV in patients with cirrhosis with a viral etiology. However, endoscopy remains the gold standard for EV screening.
